Review on ☕ Mighty Mug Gray Plastic Travel Mug, Double Wall Tumbler for Cold and Hot Drinks, No-Spill Design, Cup-Holder Friendly, Dishwasher Safe, 12oz Capacity by Rebecca Colon

Bought this for my accident prone roommate for her birthday and she loves it! Now she doesn't have to worry about spilling her morning coffee or afternoon tea on important documents or craft supplies. I've had one of these mugs for several years now and it still works just as well as the day I bought it. That! A tip: make sure the surface you plan to place the mug on doesn't have any crumbs or wet spots (or a layer of dust); Such small obstacles can cause the floor to not "stick" properly to the surface. Also make sure there is no water under the rubber ring on the bottom after washing as it may cause the same problem.
